Strengths:    Quality and Durability

Weaknesses:    None

Bottom Line:   
Excellent crankset for the dollar/weight ratio...My only wish would be if SHIMANO would shave weight off the 50T ring. but then again if that we're to happen I'm sure it would weigh in less then the Dura Ace Crankset that SHIMANO is hitting you over the head on. You will not go wrong with this crankset, it is flawless in design.

Strengths:    Smooth and quiet, compact crank, light weight

Weaknesses:    maybe less durable

Bottom Line:   
I went from a triple crank on my Marin hybrid to this, the Shimano Ultegra FC-6750 compact crank with Ultegra BB-6700. The difference in smoothness and easy shifting was immediately noticeable. So easy to setup a front derailleur for a double than a triple!!! Actually, my first crank I received had one of the teeth dinged for some reason so I had to get a replacement. Made me wonder how strong these lightweight parts really are. Can't argue with the performance and a good value compared to the uber expensive Dura Ace crankset.

Strengths:    Beautiful Crank, Shifts great! Stiff, Light

Weaknesses:    Just that it cracked, might be a bad design due to how fast the thin outer piece of the hollow chainring cracked

Bottom Line:   
This crank looks awesome and functions really well! It came stock on my bike and I loved everything about it until about a week ago. I noticed an issue when shifting up so I decided to take it off the bike and clean it up/regrease the BB area. Upon taking it off I noticed a pretty big problem..one of the shift pins had pulled through the outer ring and could wiggle in/out. Looking closer I noticed that the area around the shift pin was cracked. Although this was the only shift pin out of the four that had pulled through, 2 others had warped the area of the chainring surrounding them and had partially cracked the metal. I took photos of the shift pins before bringing it to my shop for warranty and after zooming in on the shift pins in the photos...you can clearly see that the metal shift pin has fatigued way past what it should have after only 900 miles. There were cracks in the metal all over the shift pin and I guess the best way to describe it would be to say that it looked like a piece of dried clay left out or crackled mud.

Strengths:    Much lighter than Rival crank it replaced. There is noticeable change in power transmission to the bike. Out of saddle climbing is smoother and less tiring. Shifting is smoother and faster, particularly front.

Weaknesses:    Price

Bottom Line:   
Stiff. light, much improved shifting and almost complete lack of flex comparing to the Rival compact crank I used before.
